2 Claims.

Our invention relates to an improved method in the art of making gloves and to an improved device or improved devices for improving the manufacture of gloves.

One of the objects of the invention is to provide a trank or blank having suitable openings or perforationsthrough which the needle can be passed, in the operation of sewing the glove, so i that it is unnecessary to force the needle through 110 the material of the glove during the sewing operation.

Another object of the invention is to provide improved die means, whereby said perforations are formed simultaneously with the cutting out of the trank, and said perforations are in proper position and alignment relative to the edge of the trank, in order to receive the sewing thread. Whenever we refer to a glove trank or blank, it is to be understood that we include the various parts of a glove, which are cut separately, and then sewed to each other. The invention can be used in connection with one or more such parts. Other objects are to provide means for making the improved blank, which means can be made at low cost and which shall be simple to operate. Other objects of our invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above statement of the objects of our invention is intended generally to explain the same without limiting it in any manner.

Heretofore in manufacturing a glove of leather or the like, it has been common practice for many years to cut the various portions of the glove from sheets of leather, by means of cutting .q-

dies. These portions of the glove were then sewed by hand. In using the needle, it was necessary to force the same through the material of the glove and this was tedious and difficult Work, especially if the glove was made of heavy leather.

While the invention applies to gloves made of all materials, it is particularly useful in connection with the manufacture of gloves made of leather or other material which is difficult to perforate. Likewise work done according to the former method was time-consuming, because it was necessary to make the stitches of uniform length and such work was often irregular and unevenly spaced.

According to the improved method and mechanism, the cutting dies are provided with piercing members which form the thread holes, simultaneously with the cutting of the blank, so that prior to the sewing, the blank is provided with preformed holes for receiving the sewing thread, i said holes being evenly spaced and being arranged in suitable parallel relation to the edge or edges of the blank.

Fig. 1 shows a die I, for cutting and perforating the main portion of the glove. This die has a base 2.

The front edge of the base 2 is provided with an adjustable support 3, which is of angular cross-section, and which is used for supporting one of the cutting knives and two series of perforating members. I As shown in Fig. l and Fig. 8, said supporting member 3 is provided with lugs 3a having longitudinal slots 3' and t. Clamping screws 5 adjustably connect the lugs to to the base 2, so that .the member 3 can be adjusted to and fro along a longitudinal line, and said member 3 can then be clamped in adjusted position.

The member 3 has a knife 4 detachably connected thereto by any suitable means, such as fastening members 6. An angular support 1 is connected to the member 3, by means of fastening members 8. The members 3 and 1 have smooth and snugly abutting adjacent faces.

Perforating members P are held in the member I.

In this particular embodiment two parallel rows of members P are supported in member I, as shown in Fig. 1.

In finishing the rear edge of the blank, said rear edge is turned inwardly until the holes which have been formed by the two series of members P are superposed in aligned pairs, and the sewing thread T is then passed through said aligned pairs of holes, as shown at the bottom of Fig. 19.

The piercing members P have pointed portions of the usual type, and they also have shanks which may be cylindrical or slightly tapered. A slightly tapered shape is preferred.

The tapered shanks of the piercing members P are located removably in bores of corresponding shape which are provided in the member I. Hence members P cannot move outwardly relative to member 1, but members P can be moved inwardly relative to member I, and be separated therefrom, when member I is'separated from member 3. Hence, if a piercing member P becomes blunt or broken, the member 'I can be detached from the member 3, and the defective piercing member P can be readily removed and replaced.

The inner ends of the piercing members P rest upon the adjacent surface of the member 3. Hence it is unnecessary to provide solder or any permanent connection between the piercing members and member I, although such permanent connection could be used if desired.

In the particular embodiment illustrated, a longitudinal slit is formed in the body of the glove, at the line 9 which is indicated in Fig. 16.

Itis to be understood that many different types of gloves can be manufactured by suitably varying the cutting knives or cutting members, and that the invention is not to be limited to the particular type of glove which is illustrated herein.

The slit along the line 9 is formed by the knife Ill, which is shown in Fig. 1 and in, Fig. 9. Perforations are also formed adjacent the slit 9, ac-

cording to the design indicated in Fig. 16, by means of piercing members P'- which are arranged according to a corresponding design; as shown in Fig. 1.

The knife I0 is connected removably or in any other suitable manner, to the support II. piercing members P are of the same general construction as the piercing members P. Said piercing members P are located in bores of a supporting member I2.

The member I2 is connected to the member I I, by means of screws or other fastening members I5.

The butt ends of the piercing members P are therefore supported upon the adjacent surface of the member II. V

Clamping screws or bolts I4 have their shanks passing through slots I8 of the member II. The threaded ends of the members 14 are connected to the correspondingly threaded walls of bores or recesses which are formed in the base 2.

' Therefore the assembled members II, I2 and P can be adjusted longitudinally. v

As shown in Fig. l, the knife l9 projects beyond the rear edge of the top wall of the member 1, so that the rear end of the knife I0 abuts the transverse knife 4. The members 3 and II are longitudinally adjusted simultaneously, so as to preserve said relative positions *of the knives 4 and I0. 1 l

The

Therefore, the longitudinal slit which is formed by the knife II], will extend to the rear edge of the glove blank at all times.

The side edges of the principal glove blank, and the finger portions of said principal blank, are cut by means of knives II, I8, I9, 20, 2|, 22, 23 and 24. These knives are made of the shape shown in Figs. 1 and 2 and portions of the adjacent edges of the knife members I! and I9 closely abut each other, as indicated in Fig. 1.

This is also clearly shown in Fig. 4.

Knives I8 and 24 also have abutting edge portions. These abutting edge portions act like single knife edges.

Base 2 has integral upstanding flanges 2a and 217.

As shown in Figs. 4 and 5, knife I1 is connected to flange 2a by screws 28. I

Knife I8 is connected to flange 25 by screws 21.

Angular supports 28 and 28a are detachably connected to flanges 2a and 217, by screws 29.

Said supports 28 and 29a abut the rear walls of blocks I1 and I8. 7

Piercing members [10 and I are respectively mounted in supports 28 and 28a, which are connected to flanges 2a and 2b by screws 29.

Piercing members IIa and I8a are mounted respectively in the blocks I1 and I8.

These blocks I1 and I8 are connected to flanges 2a and 2b by screws 25.

The knives I1 and I8 are respectively connected to the blocks I1 and I8 by screws 26 and 21.

Knives I9, 29, 2|, 22, 23, and .24 are clamped between the blocks B and between the corresponding blocks I8, 29', 2|, 22', 23', and 24. Said knives can be secured detachably to said blocks I924.

Blocks B are connected to base 2 by bolts 26a, whose heads are located in countersunk recesses which are provided in the top surfaces of blocks B.

Piercing members I9a, 20a, Zia, 22a, 23a, 24a. are respectively mounted in blocks I9--24, which are detachably connected to blocks B, by screws 25.

The type of glove which is disclosed herein, is provided with triangular inserts 50, at the bases of the finger portions of the glove. These inserts 50 are made from the triangular blanks 5 I, which are shown in Fig. 16. V 3

Three of such triangular inserts are provided. These inserts are cut by means of knife members 39, 30 and 38?. The knives 39 and 30 are directly adjacent the knives I9 and 24. The knife members 39 and 30 and their associated parts are 0 identical construction.

This construction and assembly are shown in Fig. 6, which shows the knife 30 connected by a screw 33 to a block 32 which has the same triangular shape as said knife 30. Said screw 33 also connects the blocks 32 to the adjacent block B.

The piercing points 3Ia which are associated with. the knife 39, are held in a supplemental block 3| which is connected to the block 32 by means of suitable screws or other fastening members.

As shown in Fig. 1, a portion of'the knife 30 is close to a portion of the knife 34 so that said closely adjacent portions form a single cutting edge.

As shown in Fig. 1 and in Fig. '7, the knife member 39 consists of two branches in angular relation, the third edge of said knife member 3|] comprising a portion of the knife 34. The knife 34 is connected to a block 35 which is connected to the 15 base 2, by means of screws or other fastening members 36. The shanks of said screws 36 pass through longitudinal slots 31 of said block 35 so that the block 35 can be longitudinally adjusted. Piercing points 34a are held in three separate blocks or holders 38, 39, 4|].

The blocks 38 and 39 are of angular cross-sec tion as shown in Fig. '7 and they are connected to the member 35 by screws or other suitable fastening devices. The block 40 is connected to the block 35, by means of fastening screws 4 I.

The piercing points are held in said blocks 38, 39 and 40, in the manner previously described.

Piercing points 42 are also associated with the knife member 30 and said piercing points 42 are held in the block 43, which is connected by means of a screw 44 to a block 45. Said block 45 is held to the block 35 by means of a screw 46 whose head is countersunk in the corresponding surface of the block 35.

In the particular embodiment described, decorative stitching is provided along the lines 52. The perforations for said lines of decorative stitching are formed by piercing points 41 which are held in a block 48. Said block 48 is connected by suitable screws to a block 49, which is held to the base 2 by means of bolts 60.

The bolts 60 have their shanks passing through longitudinal slots 6| of the blocks 49, in order to permit longitudinal adjustment of the block 49.

In order to use the device illustrated in Fig. 1, a sheet of leather or other suitable material is placed upon the edges of the cutting knives and over the piercing members, and suitable pressure is applied to the sheet of leather by means of members made of wood or other material which can be easily pierced or out.

For example the leather blank may be laid upon a wooden table and the device shown in Fig. 1 can be inverted and pressed against said leather blank so as to cut and perforate said leather blank.

The triangular pieces which are formed by the knife members 30 and 30' and 311 preferably remain integral with the main body of the blank, as illustrated in Fig. 16.

The thumb piece 53 of the glove is formed by the die member 62, having a knife 63 connected thereto by means of screws 62a. The piercing members 63a are held in a block 64, which is suitably connected to the member 62 by means of screws65.

In the particular embodiment shown, the finger portions of the glove are provided with the usual inserts 54. Said inserts 54 are cut by means of a die member 10, having the knife 66 connected thereto by means of screws 61. A slitting knife 66a is detachably mounted in member 15, and it is clamped between blocks 69 and 69',"which are connected by screws 65 to member 10. Piercing members 68 are mounted in blocks 69 and 69'.

Generally speaking, the dies for cutting out the sections of the glove can be of the usual type practice for any further details of the dies and of I their knives, and of the gloves.

The glove member which is formed by the die illustrated in Fig. 13 is the member 54 which is shown in Fig-18.

Figs. 19-21 conventionally illustrate the assembly of various parts of the glove. These figures also show the sewing thread T which is passed through the sewing perforations S which have been formed by the piercing points.

Therefore the operator has a sure and reliable guide for assembling the portions of the glove blank in proper relation, thus providing sewing which is absolutely uniform and of high quality.

According to the invention, the thread-receiving perforations are formed while cutting the blank. However, the invention is not limited to a methodwhereby the cutting means and the perforating means operate simultaneously. It is preferred to have the piercing members penetrate the material before or while the cutting means operate, but this is not absolutely necessary, and the invention is not to be so restricted. The preferred device shows the cutting means and the perforating means rigidly connected to the base of the device, and immovable relative to said device, while the device is being used. However, it would not be departing from the invention if the perforating means or the cutting means, or both, were mounted movably relative to the base, so as to move perpendicular to the base. In such case, it is preferred to have the knives and piercing members operate in fixed lateral relation, so that the perforations are formed accurately relative to the edges or slits which are formed by the knives.

All the parts of the device are detachable from each other and from the base or its flanges. The piercing members and their supports are generally of the same construction, so that the butt ends of the piercing members abut rigid surfaces of the die-means, and defective piercing members can be readily replaced.

Numerous changes and omissions can be made in the details herein, without departing from the spirit of the invention.

We claim:

1. A device for cutting a glove blank and for perforating thread-receiving openings in said blank, said device having cutting means for cutting the blank, said device also having perforated supporting means, perforating members removably located in the perforations of said supporting means, said perforating members having pointed portions which project outwardly of said supporting means, each said supporting means being connected to a base member, the inner ends of said perforating members abutting a surface of said base member.

2. A device for cutting a glove blank and for perforating thread-receiving openings in said glove blank, said device having cutting means for cutting the blank, said device also having perforated supporting means connected thereto, perforating members removably held in operative position in the perforations of said supporting means, said perforating members having pointed ends which project outwardly of said supporting means, and additional means removably connected to said supporting means and holding the perforating members against inward movement relative to said supporting means.
